Servicing the Array

Note –
Even if the LED indicates an interconnect card failure, you should always
verify the FRU status using either the CLI or Sun StorEdge Component Manager
before replacing the unit. Refer to the Sun StorEdge T3+ Array Administrator’s Manual
or Sun StorEdge Component Manager User’s Guide for more information.

To Removing and Replacing an Interconnect Card
Caution –
Use the interconnect cables to cable only Sun StorEdge T3+ arrays
together using the interconnect card connectors. Do not use these cables for any
other FC-AL connection.
Caution –
The interconnect card FRUs are extremely sensitive to static electricity.
Use proper grounding wrist straps and antistatic procedures when handling these
FRUs. See Section , “Preparing for Service” on page 14-165 for a list of static
electricity precautions.
Caution –
Replace one interconnect card at a time. Follow the procedure as
described to ensure that there is no interruption in system operation or loss of data.
To prevent interruption of system operation during interconnect card replacement,
make sure that:
■
In a workgroup configuration, you remove only the failed interconnect card.
Leave the second interconnect card intact in the array.
Caution –
Removing both interconnect cards at the same time in a single unit will
cause the unit to shut down immediately. Remove only one card at a time.
■
In an enterprise configuration, you remove the interconnect cable only from the
failed interconnect card. Leave the interconnect cable attached to the working
interconnect card.
To replace an interconnect card:
1. Ensure that the interconnect card to be replaced is showing failure status.
2. Observe static electricity precautions, as described in “Preparing for Service” on
page 165.
If you have a single controller unit configuration, proceed to Step 4.
